Multi-criteria decision approach with stakeholders for food waste management

Abstract

The activities related to agri-food production and the disposal of its waste account for a large number of greenhouse gas emissions. In many cases, food waste (FW) management is established by making a single assessment for its sustainability based on economical or environmental impacts. However, social impact assessments on stakeholders are often incomplete or missing, and its efficiency is seldom measured. Decision-making in waste management strategies, such as the acquisition of appropriate waste treatment sites or methods used, frequently involves multiple stakeholders such as government, municipalities, industries, experts, or public sectors. Due to the complication of differing criteria and alternatives in FW management technology, a multi-criteria decision-making (MCDM) methodology is recommended to certify the quality of the decision-making process. This paper reviews the use of MCDM as decision supporting techniques in modelling and analysing decision making in situations with multiple stakeholders for FW management. The synthesis results obtained through the MCDM tool will be more reliable when requesting confirmation from stakeholders based on a recommended minimum range of criteria for each sustainability dimension in the FW issues. Finally, potential studies in this area have been proposed.

Comparison and Selection of Wet Waste Disposal Modes for Villages in Agriculture-Related Towns Taking Shanghai, China, as an Example

“…The process of MCDM for solid waste disposal typically involves three main steps: criteria selection, weight determination, and alternative ranking [35][36][37][38][39]44].…”

“…To determine the weight of the five criteria and rank the three alternatives, fuzzy analytic hierarchy process (FAHP) analysis was used in this study. AHP, TOPSIS, PROMETHEE, VIKOR, and other approaches are widely used in MCDM analysis [35][36][37][38][39]44]. AHP or a combination of AHP and another method is the most commonly employed MCDM method [34,44].…”

Among these methods, the FAHP method, which combines the fuzzy logic theory with AHP, optimizes the deficiencies of the traditional AHP method.…”

Multiple-Criteria Decision Analysis Using TOPSIS and WSA Method for Quality of Life: The Case of Slovakia Regions

“…The multidimensional concept can be covered by five dimensions: physical well-being, material well-being, social well-being, emotional well-being, development and activity. This model highlights the specific problems of the individual, as well as of the entire population [16,17]. The quality of life is closely linked to the quality of the environment.…”
